Microsoft Security Response Center
Microsoft Security Response Center (MSRC) is a threat intelligence feed for security vulnerabilities impacting Microsoft products and services. You can use the MSRC connector to pull MSRC CVRF (Common Vulnerability Reporting Framework) monthly updates and CVE (Common Vulnerabilities and Exposures) data into the Brinqa Platform.
This document details the information you must provide for the connector to authenticate with MSRC and how to obtain that information from Microsoft. See create a data integration for step-by-step instructions on setting up the integration.
Required connection settings
When setting up a data integration, select Microsoft Security Response Center from the Connector drop-down. If you cannot find the connector in the drop-down, make sure that you have installed it first. You must provide the following information to authenticate MSRC with Brinqa:
-
API URL: The MSRC API URL. The default URL is
https://api.msrc.microsoft.com. -
API version: The year of the MSRC API version. The default API version is 2024.
Types of data to retrieve
The MSRC connector can retrieve the following types of data from the MSRC API:
Table 1: Data retrieved from MSRC
| Connector Object | Required | Maps to Data Model |
|---|---|---|
| Product | No | Not mapped |
| Security Bulletin | Yes | Security Advisory |
| Security Update | Yes | Vulnerability Definition |
The MSRC connector does not currently support operation options for the types of data it retrieves.
For detailed steps on how to view the data retrieved from MSRC in the Brinqa Platform, see How to view your data.

Security Bulletin
Table 2: Security Bulletin attribute mappings
| Source Field Name | Maps to Attribute |
|---|---|
| ALIAS | Local variable |
| ISSUING_AUTHORITY | Local variable |
| LAST_UPDATED | sourceLastModified |
| RELEASE_DATE | publishedDate |
| RELEASE_NOTES | description |
| SYS_ID | uid |
| TITLE | name |
Local variable indicates that the field is processed within a specific context, such as a particular workflow or calculation. Unlike other attributes, local variables aren't mapped to the unified data models (UDM). They only exist on the source data model (SDM).
Security Update

Local variable indicates that the field is processed within a specific context, such as a particular workflow or calculation. Unlike other attributes, local variables aren't mapped to the unified data models (UDM). They only exist on the source data model (SDM).
Use CVSS calculator indicates that the CVSS (Common Vulnerability Scoring System) vectors and scores aren't directly mapped to a specific attribute on the UDM. Instead, a specialized library calculates the CVSS scores from the provided CVSS vector strings.
APIs
The MSRC connector uses the MSRC CVRF API. Specifically, it uses the following endpoints:
Table 4: MSRC API Endpoints
| Connector Object | API Endpoints |
|---|---|
| Product | /cvrf/{updateID} /updates |
| Security Bulletin | /cvrf/{updateID} /updates |
| Security Update | /cvrf/{updateID} /updates |
For additional information about the specific API endpoints, please see the MSRC CVRF API Swagger JSON.
